Making McCain Secrtary of War would get him out of the Senate, where he wields disproportionate power, especially when paired with Senator Graham.
McCain’s final stint in the Navy was as CO of RAG-174. By all accounts, he performed admirably.
John McCain is not a well man. He would last a year, at most as Secretary of War. Those of us who served with him in Vietnam would appreciate the conciliatory gesture by President Trump.
And, yes, General Flynn would make a splendid choice to serve as the second Secretary of War in modern times.
You do make an interesting case. I trust Trump having good judgment in his choices of a team, and pray that in all things he is granted guidance from on high. So far IMHO, he seems to be doing pretty well! If he places McCain in a position of authority, I really will be surprised, but will accept it if he judges that to be the best place for him.
But McCain has really ripped his knickers with me by his actions in the Senate over the years big time!
Not wishing him any harm, and hope for his total healing, body, mind, and soul in whatever is the Lord’s perfect place for him at the perfect time, whatever and wherever that may be.
